Chevrolet Silverado 2500 Upper Coolant Pipe by Wehrli, Sparkle Granny Smith, 2020–2025. This aluminum pipe replaces the factory rubber upper radiator hose on L5P 6.6L Duramax trucks for a clean, durable upgrade.

Designed for stock trucks with the OEM GM radiator, it installs with basic hand tools and requires no modifications. A tough powder coat resists heat and grime, while the fabricated aluminum construction offers long-term durability. The kit includes silicone boots and stainless T-bolt clamps, and cross-references GM 84813629 and 85122989. Fits 2020–2025 Chevrolet Silverado and GMC Sierra 2500/3500 with the L5P. Note: for use with OEM GM radiator; aftermarket radiators may cause fitment issues.
